Objective To study the method of integrated design with reliability, testability, maintainability and supportability（RTMS） under model-based system engineering. Methods The fault model provided by Altarica language was applied to develop the model of reliability and testability. The quantitative analysis of the preventive maintenance task was completed with the help of durability simulation technology in the multi-body dynamics simulation environment. Results Taking the system fault model derived from the complex system function model as the bond, according to modeling and simulation of RTMS, the RTMS integrated design satiable with operational scene can be achieved with the help of RTMS modeling and simulation technology. Conclusion The integrated design for RTMS can be achieved under model-based system engineering.
